He aha ngā āhuatanga o te karāpiti whakawhanui i muri i te whakamahanatanga hei karāpiti whakawhanui?

Ngā āhuatanga whānui opepa karāhe ka taea te whakawhānuihe rerekē i ētahi atu kaihopu whakawhanui. Ina werahia ki tētahi pāmahana, ka tīmata te whakawhanui o te karāpeti whakawhanui nā te pirau o ngā matū e mimitihia ana i roto i te whatunga paparanga, e kiia nei ko te pāmahana whakawhanui tuatahi. Ka whakawhanui katoa i te 1000 ℃ ka tae ki te rōrahi mōrahi. Ka taea e te rōrahi whakawhanui te eke ki te neke atu i te 200 ngā wā o te uara tīmatanga. Ka kiia te karāpeti whakawhanui ko te karāpeti whakawhanui, ko te kutukutu karāpeti rānei, e huri ana mai i te āhua paparanga taketake ki te āhua kutukutu me te iti o te mātotoru, ka hanga he paparanga whakamahana tino pai. Ehara i te mea ko te karāpeti whakawhanui he pūtake waro anake i roto i te pūnaha whakawhanui, engari he paparanga whakamahana anō hoki. Ka taea e ia te whai huaārai i te weraI roto i te ahi, he iti ōna āhuatanga o te tere tuku wera, te iti o te ngaronga papatipu, me te iti o te hau paru.

He aha ngā āhuatanga o te karāpiti whakawhanui i muri i te whakamahanatanga hei karāpiti whakawhanui?

Ngā āhuatanga o te karāwhata kua whakawhanuitia

① Te ātete kaha ki te pēhanga,ngāwari, te kirihou me te whakahinuhinu-ake;

② He ātete kaha ki te pāmahana tiketike, iti,waikurame te irahiko;

③ Ngā āhuatanga rū whenua tino kaha;

④ Tino kahakawe hiko;

⑤He āhuatanga kaha hei ārai i te koroheketanga me te whakapōturi.

⑥ Ka taea e ia te ātete i te rewa me te urunga o ngā momo konganuku;

⑦ Kāore he paitini, kāore he matū whakaputa mate pukupuku i roto, ā, kāore hoki e kino ki te taiao.

Ko ētahi o ngā huarahi whanaketanga o te karāwhata whakawhanui koia ēnei:

1. Karāpeti whakawhanuitia mō ngā kaupapa motuhake

E whakaatu ana ngā whakamātautau he mahi tā ngā kutukutu karāpeti ki te mimiti i ngā ngaru hikohiko. Me tutuki i te karāpeti whakawhanui ngā whakaritenga e whai ake nei: (1) he iti te pāmahana whakawhanui tīmatanga me te nui o te rōrahi whakawhanui; (2) he pumau ngā āhuatanga matū, ka rongoatia mō te 5 tau, ā, kāore te ōwehenga whakawhanui e pirau; (3) he koretake te mata o te karāpeti whakawhanui, ā, kāore he waikura ki te pouaka kātere.

2. Karāpeti whakawhanui porotaka

Ko te karāpeti whāwhā iti e pā ana ki te karāpeti whāwhā 300 mata me te rōrahi whāwhā o te 100ml/g. Ko te nuinga o tēnei hua e whakamahia ana mō te aukati mura.ngā paninga, he mea e tino hiahiatia ana.

3. Karāpeti whakawhanui me te pāmahana whakawhanui tīmatanga teitei

Ko te pāmahana whakawhanui tuatahi o te karāwhata whakawhanui me te pāmahana whakawhanui tuatahi teitei ko te 290-300 ℃, ā, ko te rōrahi whakawhanui he ≥ 230ml/g. Ko tēnei momo karāwhata whakawhanui te nuinga e whakamahia ana mō te aukati mura o ngā kirihou hangarau me te rapa.

4. Karāpeti mata kua whakarerekētia

Ina whakamahia te karāpiti whakawhanui hei rauemi ārai mura, ka uru atu ki te hototahitanga i waenga i te karāpiti me ētahi atu wāhanga. Nā te nui o te kohuke o te mata o te karāpiti, ehara i te mea he lipophilic, he hydrophilic rānei. Nō reira, me whakarerekē te mata o te karāpiti kia ea ai te raruraru o te hototahitanga i waenga i te karāpiti me ētahi atu wāhanga. Kua whakaarohia kia whakama te mata o te karāpiti, arā, kia kapi te mata o te karāpiti ki te kiriata mā totoka, he raruraru uaua ki te whakaoti. Kei roto ko te matū kiriuhi, te matū mata rānei. Tērā pea ka taea e te taiwhanga te mahi pēnā, ā, he uauatanga kei roto i te ahumahi. Ko tēnei momo karāpiti whakawhanui mā te nuinga o te wā ka whakamahia hei paninga ārai mura.

5. Te pāmahana whakawhanui tīmatanga iti me te karāhe whakawhanui pāmahana iti

Ka tīmata te whakawhanui o tēnei momo karāpiti whakawhanui i te 80-150 ℃, ā, ka eke te rōrahi whakawhanui ki te 250ml/g i te 600 ℃. Ko ngā uauatanga o te whakarite karāpiti whakawhanui hei whakatutuki i tēnei āhuatanga ko: (1) te whiriwhiri i te kaihoko whakauru tika; (2) te whakahaere me te matatau ki ngā āhuatanga whakamaroke; (3) te whakatau i te makuku; (4) te whakaoti rapanga tiaki taiao.
